The Society of Biology is recruiting you (yes you) to help research the lives of UK spiders around the home. You can record sightings online, and there's even an app available for iPhone and Android to make it easy to send in reports and identify species.

This is the time of year when male house spiders typically come inside our homes, looking for love. But surprisingly little is known about them. That's where you can help!

The BBC also has a great article about the survey, including a quick rundown of common species. It alerted me to the Cardinal spider, the UK's largest house spider, which can have a leg span up to 14cm according to Wikipedia, brilliantly illustrated with one comfortably straddling a floppy disk. Remember floppy disks?
